Successfully treated urethral condyloma acuminatum utilizing intraurethral self-application of 5-fluorouracil via Q-tip.

Condyloma acuminatum is a benign genital lesion associated with low-risk human papillomavirus subtypes. Approximately 20% of HPV-associated genital warts occur in the urethra. Topical treatment of urethral condyloma in women can be challenging to treat due to difficulty applying the medication such that it maintains contact with the urethra long enough to be effective. We present a case of a successfully cleared urethral condyloma acuminatum treated via self-application using a Q-tip.

Female urethral condyloma acuminata mimicking urethral caruncle.

Condyloma acuminata are epidermal lesions caused by the human papillomavirus (HPV) most commonly affecting the anogenital region. Urethral involvement is uncommon, and may mimic other urethral lesions. In this case report, a 62-year-old patient presents with what was believed to be a urethral caruncle and underwent successful resection with the final pathologic diagnosis of urethral condyloma. The clinical features and diagnosis are reviewed. This condition should be considered in the differential diagnosis of females with known HPV or those who are deemed higher risk with unprotected sexual encounters.

Post-hypospadias urethrocutaneous fistulae: no difference in repair success between proximal and distal fistulae.

INTRODUCTION Urethrocutaneous fistulae are the most common complication after hypospadias repair. We sought to compare outcomes of proximal versus distal urethrocutaneous fistula repair and hypothesized that patients with proximal fistulae would have lower rates of success than those with distal fistulae. We also aimed to evaluate factors that affected these outcomes. MATERIAL AND METHODS: Current procedural terminology codes were used to identify patients undergoing urethrocutaneous fistula repair after hypospadias surgery between 2014 and 2017 at an academic, pediatric urology referral center. Characteristics for each initial hypospadias repair and each fistula repair were noted, including location of meatus, location of fistula, type of magnification, suture type, interposition layer and post-operative stenting. The primary outcome was successful fistula repair. Univariate and multivariate analysis was performed. RESULTS: During the study period, 416 hypospadias repairs were performed. Thirty-one of these later presented with a fistula (8% fistula rate). Sixty-eight percent of fistulae were successfully closed with a single repair. There were 17 distal fistulae and 14 proximal fistulae. There was no difference in success between distal (71%) and proximal (64%) fistulae (p = 0.73). There was no statistically significant association between the primary outcome (successful fistula repair) and fistula location (p = 0.71), magnification (p = 0.38), suture type (p = 0.49), interposition coverage layer (0.43), or postoperative stenting (p = 0.92) on univariate or multivariate analysis. CONCLUSION: There is no difference in success when repairing distal versus proximal urethrocutaneous fistulae. Neither fistula location, type of magnification, suture type, interposition layer nor stenting affected outcomes.

Translabial ultrasound imaging of urethral diverticula.

OBJECTIVE: Urethral diverticulum is an uncommon cause of urinary dysfunction in women, with often a significant delay in diagnosis. Urethroscopy and/or magnetic resonance imaging are/is widely used for its identification. Translabial ultrasound is an alternative, particularly since the introduction of three-/four-dimensional imaging. The aim of our study was to review 10 years' experience of urethral diverticula evaluated by translabial ultrasound. METHODS: We reviewed 4121 patients seen in a tertiary urogynecologic unit between 2008 and 2018. All women were examined using multiplanar translabial ultrasound as well as office urethroscopy. Data regarding demographics, presenting symptoms and findings on clinical examination were collected. Archived ultrasound volumes were analyzed for diverticular location, diameters, complexity and echogenicity as well as tract visualization. RESULTS: Of our study population, 23 (0.6%) were found to have a major urethral abnormality on translabial ultrasound, 15 of whom were confirmed to have a urethral diverticulum on urethroscopy. Of these, 12 had a cystic component and three were non-cystic on imaging. Mean maximum diameter was 15.3 mm (range, 4-32 mm). In 9/15 there was a simple diverticulum, while in 6/15 it was classified as complex. A communicating tract was seen in 10/15 (67%), and this was located at the 5-7 o'clock position in 7/10 (70%). Mean urethral circumference covered by the diverticulum was 39%. CONCLUSIONS: Translabial ultrasound is a valid, non-invasive method for the diagnosis of urethral diverticulum. A cystic structure crossing the urethral rhabdosphincter has high predictive value for urethroscopic diagnosis of urethral diverticulum. Multiple hyperechogenic foci may indicate the presence of a small urethral diverticulum. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Fact or myth? The long shared common wall between the fistula and the urethra in male anorectal malformation with urethral bulbar fistula.

AIM: It has long been considered surgical dogma that the length of the shared common wall (CW) between a fistula and the urethra in males with anorectal malformation (ARM) and rectourethral bulbar fistula (RUBF) is considerably longer than in males with ARM and rectourethral prostatic fistula (RUPF). This belief has led surgeons who perform laparoscopic-assisted anorectoplasty (LAARP) for RUPF to avoid LAARP for RUBF for risk of potential injury to the urethra or incomplete removal of the fistula. In this study, we compared CW between RUBF and RUPF using distal colostography (DCG) and direct intraoperative measurements. METHODS: DCG of rectourethral fistula patients (n = 63; RUBF: n = 44; RUPF: n = 19) were used to measure CW retrospectively. Results were expressed as a ratio of the height of L4; i.e., CW:L4. If less than 0.7, the CW was classified as being "short"; if 0.71-1.4, as being "medium"; and if greater than 1.41, as being "long". CW that could not be measured was classified as indeterminate. 24 of these patients also had CW measured intraoperatively during LAARP as previously described. The results obtained using both techniques were also compared. RESULTS: Surprisingly, CW:L4 in RUBF patients was short in 47.7%, medium in 27.3%, long in 20.5%, and indeterminate in 4.5% on DCG, equivalent to mean lengths of 7 mm, 8.5 mm, and 10.3 mm obtained using direct intraoperative measurement for short, medium, and long CW:L4 categories, respectively. CW:L4 in RUPF was short in 73.6%, medium in 10.5%, and long in 5.2% on DCG, while mean intraoperative measurements were 5 mm, 7 mm, and 10 mm, respectively. Differences in CW measured intraoperatively were not significantly different between RUBF and RUPF (p = NS). CONCLUSION: From our findings, 47.7% of CWs in RUBF were short using two independent methods, with only 20.5% being long. Thus, LAARP should be considered actively for treating selected RUBF cases and not be excluded on the basis of CW length.

Ultrastructural Analysis of Urethral Polyps against the Background of Urogenital Infection.

We performed an electron microscopic study of samples of urethral polyps obtained from 90 women (mean age 52.5±4.9 years). According to PCR and culture studies, the most common infectious agent in patients with urethral polyps is U. urealyticum (100% cases). In 70% cases, this infectious agent was present as monoinfection, of these, clinically significant concentration (>106 CFU/ml) were found in 53.3% cases. In 30% cases, associations with C. trachomatis, T. vaginalis, and M. genitalium were found. We observed significant ultrastructural heterogeneity of the epithelial cells in urethral polyps, which manifested in a combination of hyperplastic and metaplastic changes and signs of cytodestruction. Detection of mycoplasma-like bodies in connective tissue mononuclear cells and viral particles in epithelial cells during ultrastructural study, including cases with negative PCR results, indicates the pathogenetic role of latent infection in the formation of urethral polyps.

Impact of Radiation and Transcorporeal Artificial Sphincter Placement in Patients with Prior Urethral Cuff Erosion: Results from a Retrospective Multicenter Analysis.

PURPOSE: Many providers elect to use a transcorporeal approach for artificial urinary sphincter placement in an attempt to minimize risks, given the increased risk of complications in revision cases. We present outcomes in a multicenter retrospective analysis of artificial urinary sphincter cuff reimplantation in patients with prior cuff erosion with special consideration given to the transcorporeal approach. MATERIALS AND METHODS: We compiled a multi-institutional database of patients who underwent artificial urinary sphincter reimplantation after prior urethral erosion. Of the 34 identified patients 24 underwent transcorporeal cuff replacement. Patients with transcorporeal cuff replacement were further analyzed with specific stratification for radiation therapy. RESULTS: The rate of subsequent complications after eroded cuff reimplantation was 32.4% (11 of 34 patients). The most frequent complication was recurrent erosion, which developed in 9 of the 34 patients (26.4%). Repeat artificial urinary sphincter complications developed more frequently in patients with history of radiation compared to nonirradiated patients (8 of 16 or 50% vs 3 of 18 or 16.7%). However, this difference was not statistically significant (p = 0.066). The transcorporeal technique was applied in 24 of 33 patients (70.5%) and relative to the nontranscorporeal group there was no difference in the complication rate (p = 0.438). On subgroup analysis of the transcorporeal group there was a higher rate of repeat complications in irradiated patients (p = 0.006). CONCLUSIONS: These data suggest that transcorporeal cuff reimplantation may not decrease the incidence of repeat complications after prior cuff erosion. However, radiation therapy is associated with a worse outcome even when transcorporeal cuff placement is performed.

Urethral prolapse in prepubertal females: Report of seven cases.

Urethral prolapse is a rare lesion in female children, with a suggested incidence of one in 5000 in China. Most of the cases reported in children have been in girls of African descent. In this report, we present seven cases of Chinese pediatric patients with urethral prolapse. Patient ages ranged from 2 to 8 years. They all presented with a protruding mass in the vaginal opening and bleeding. Diagnosis was confirmed with the combination of clinical manifestation and supplementary examinations. The patients were treated with either conservative therapy (two of the seven patients) or surgical intervention (five of the seven patients). During a 2-week to 6-year follow-up, no case recurred. The literature on urethral prolapse is reviewed.

Giant urethral diverticulum calculus revealed by peri-urethral abscess.

Urethral diverticulum of the male is uncommon. We report a case of bulbar urethraldiverticulum with contained giant calculus presenting as left inguino-scrotal swellingsecondary to peri-urethral abscess in a 40 year-old male. In the light of this case Weemphasize the importance of investigation for the presence of urethral diverticulum in youngmale individuals presenting with voiding disturbances to preventrelated complications.

Magnetic Resonance Imaging of a Urethral Caruncle and the Pathologic Correlation: A Report of 3 Cases.

A urethral caruncle is the most common disease of the urethra in postmenopausal women. A definitive diagnosis can usually be reached based on physical examination. Cross-sectional imaging is performed when malignant urethral tumor is suspected, such as a urethral carcinoma. No articles have discussed the detailed imaging of urethral caruncles. We present 3 patients with symptomatic urethral caruncles who underwent magnetic resonance imaging preoperatively.

A new material to prevent urethral damage after implantation of artificial devices: an experimental study.

OBJECTIVE: To validate the application of the bacterial cellulose (BC) membrane as a protecting bar-rier to the urethra. MATERIALS AND METHODS: Forty female Wistar rats (four groups of 10): Group 1 (sham), the urethra was dissected as in previous groups and nothing applied around; Group 2, received a 0.7cm strip of the BC applied around the urethra just below the bladder neck; Group 3, received a silicon strip with the same dimensions as in group 2; Group 4, had a combination of 2 and 3 groups being the silicon strip applied over the cellulosic material. Half of the animals in each group were killed at 4 and 8 months. Bladder and urethra were fixed in formalin for histological analysis. RESULTS: Inflammatory infiltrates were more intense at 4 months at lymphonodes (80% Grade 2), statistically different in the group 2 compared with groups 1 (p=0.0044) and 3 (p=0.0154). At 8 months, all samples were classified as grade 1 indicating a less intense inflammatory reaction in all groups. In group 2, at 8 months, there was a reduction in epithelial thickness (30±1µm) when com-pared to groups 1 (p=0.0001) and 3 (p<0.0001). Angiogenesis was present in groups 2 and 4 and absent in group 3. In BC implant, at 4 and 8 months, it was significant when comparing groups 4 with 1 (p=0.0159). CONCLUSION: BC membrane was well integrated to the urethral wall promoting tissue remodeling and strengthening based on morphometric and histological results and may be a future option to prevent urethral damage.

Imperforate anus with rectopenile fistula: a case report and systematic review of the literature.

BACKGROUND: Although anorectal malformations (ARMs) are frequently encountered, rare variants difficult to classify have been reported. METHODS: This study describes a patient with ARM and rectopenile fistula. The literature was reviewed systematically to assess the anatomical characteristics, clinical presentations and operations of this rare type of ARM. RESULTS: Eight patients were reported in the six included articles. In three patients, the fistula extended from the rectum to the anterior urethra without communication with the skin. In one patient, the fistula, located deep in corpus spongiosum, opened to the ventral aspect of the penis without communication with the urethra. In the remaining four patients, the fistula extended from the rectum to the cutaneous orifice in the ventral aspect of penis, with communication or a short common channel with the urethra. CONCLUSIONS: Imperforate anus with fistula extending into the penis is a rare variant of anorectal malformation. Unawareness of this lesion resulted in a delay of correct diagnosis and appropriate management. A thorough examination, including colonourethrography and fistulography, should be performed in all patients with a fistula opening in the ventral aspect of the penis.

Circumferential urethral fistulae in Sub-Saharan Africa, current outcomes and future prospects.

INTRODUCTION AND HYPOTHESIS: Circumferential urethral fistula is a severe form of obstetric injury that is recognized to carry a poor prognosis for eventual continence but this has not been quantified before. METHODS: An analysis of 106 women who had undergone primary repair of a circumferential fistula was carried out with particular reference to whether there complete continence or at least some improvement in remaining dry was reported. RESULTS: Of the 106 women, only 25% reported themselves continent; 19% said there was an improvement. Prognosis was not altered by the distance of the fistula from the external urethral meatus, with 10/62 (16% reporting continence if the fistula was <1.5 cm and 10/44 (13%) if >1.5 cm. There was a 13% primary dehiscence rate. CONCLUSIONS: Current methods of primary urethral fiistula repair carry a poor prognosis for eventual continence. Techniques to lengthen the urethra and provide greater support need to be developed for this unfortunate group of women.

Female Urethral Diverticulum: Current Diagnosis and Management.

While urethral diverticulum (UD) affects less than 20 per 1,000,000 women overall, it is thought to represent 1.4% of women with incontinence presenting to urology practices. It is hypothesized to evolve from periurethral glands that become obstructed, infected, and dilated over time, and patients typically present with dyspareunia, bothersome lower urinary tract symptoms (LUTS), and/or recurrent UTIs. In many patients, a periurethral mass can be appreciated on exam. In recent years, magnetic resonance imaging (MRI) has become the imaging test of choice for diagnosis of UD, but ultrasound (US) is a readily available alternative and provides good specificity at a lower cost. Surgical excision of the diverticulum with tension-free, water-tight, three-layer closure continues to be the mainstay of treatment of UD with most studies reporting cure rates of >90%. Concomitant treatment of preexisting stress incontinence with autologous fascial pubovaginal sling can be used at the time of diverticulectomy to avoid a secondary procedure. However, since secondary anti-incontinence procedures are needed in only a small number of patients, up-front stress incontinence treatment may result in significant overtreatment, and staged anti-incontinence procedures continue to be a reasonable option for patients with persistent bothersome stress urinary incontinence (SUI) after diverticulectomy.

Lesions of Skene glands and periurethral region: a review.

The periurethral (Skene) glands may become involved by a variety of conditions. Mass-like lesions need to be distinguished from other lesions arising from the anterior vagina. Familiarity with these lesions will be helpful if a patient with a lesion of the Skene glands or periurethral region is encountered.

[CLINICO-MORPHOLOGICAL FEATURES OF FEMALE URETHRAL MEATUS POLYPS].

The aim of the study was to establish the clinical and morphological characteristics of female urethral polyps including cases with concomitant sexually transmitted infections. A total of 150 women were enrolled in the study. The evaluation of microcirculatory changes, morphological parameters and immunogram indices of urethral polyps were carried out. The most common infectious agent in patients with urethral polyps was Ureaplasma urealyticum. In those cases predominance of inflammatory symptoms and elevated levels of serum proinflammatory cytokines were identified. It is found that the pronounced inflammatory reaction leads to an increase in the relative area of the subepithelial microvascular bed and the cellular elements population of lamina mucosa propria, as well as to the relative predominance of congestive forms of microcirculation disturbances according to the laser Doppler flowmetry.

[VIRAL INFECTIONS: HUMAN PAPILLOMAVIRUS AND GENITAL HERPES TYPE 1 AND TYPE 2 AS A CAUSE OF CHRONIC RECURRENT CYSTITIS WITH SEVERE DYSURIA IN WOMEN WITH URETHRAL HYPERMOBILITY AND HYPOSPADIAS].

Female hypospadias presenting as a misplaced urethral opening is a common cause of chronic recurrent cystitis. Cystitis occurs when urogenital infection and anaerobic bacteria enter the urethra and bladder from the vagina. The authors argue that chronic infections of the lower urinary tract in women with hypospadias should be treated surgically by meatal transposition. They present a study confirming the role of the antiviral drug Panavir in prevention of inflammatory complications in the postoperative period in patients with a history of viral infection (human papillomavirus and herpes).

[Skene duct cyst in female newborns--case reports]. / Quiste de conducto de Skene en niñas. A propósito de 2 casos clínicos.

INTRODUCTION: The Skene duct cyst, classified as a paraurethral cyst, is a rare congenital abnormality in female neonates and it may manifest throughout the course of life. The incidence varies from 1 in 2000 to 3000 female births. OBJECTIVE: To expose the characteristics and symptoms of a Skene duct cyst at different stages of child development in order to carry out a timely suspicion and diagnosis. CASE REPORT: The first case is a female newborn who presented a painless yellowish tumor adjacent to the urethral meatus, which drained spontaneously; the second case is a teenager who consulted due to leucorrhea for a year and a three-centimeter diameter paraurethral injury between the labia minora, which required surgical treatment and study of the paraurethral mass. CONCLUSIONS: Based on the literature review, we concluded that the frequency of Skene duct cyst is higher than the number of reported cases. Cyst removal, marsupialization, puncture and aspiration are all effective treatment methods. Spontaneous drainage is also appropriate in certain cases. We suggest the use of the least aggressive technique according to each case.

Intrinsic ureteric obstruction secondary to endometriosis: a rare clinical entity causing obstructive uropathy and renal failure.

Ureteral endometriosis is rare and can be a silent clinical entity, which can potentially lead to serious complications such as obstructive uropathy, sepsis and renal failure. A high clinical suspicion is required especially in childbearing age groups due to non-specific presentation such as renal colic, recurrent urinary tract infection (UTI), renal failure or asymptomatic hydronephrosis.A woman in her 40s presented with febrile UTI and flank pain. She reportedly suffered from recurrent UTIs in the past. Initial workup revealed an infected, obstructed left renal collecting system with gross hydronephrosis and hydroureter to the distal ureter on a significant gynaecological background of severe endometriosis requiring hysterectomy in the past.CT showed chronic obstructive changes and soft tissue nodules within the renal pelvis with no radio-opaque stones. She underwent emergent ureteric stent insertion. Functional imaging demonstrated only 1% contribution of the left kidney with a preserved estimated glomerular filtration rate of 65 mL/min/1.73 m2Endoscopic evaluation of ureters found extensive soft tissue lesions throughout the dilated left collecting system with biopsy-confirmed endometriosis. Subsequently, she underwent laparoscopic nephroureterectomy due to extensive ureteric involvement and chronically obstructed non-functioning kidney. Histopathology demonstrated completely obstructing ureteral endometriosis.Ureteric obstruction secondary to endometriosis can be due to extrinsic or intrinsic disease. In addition to initial assessment with CT urogram MRI may be helpful to evaluate soft tissue thickening. Endoscopic assessment with ureteroscopy and biopsy is required for tissue diagnosis. Surgery is often the treatment of choice, ranging from ureteroureterostomy, ureteroneocystostomy or nephroureterectomy in severe cases.Ureteral endometriosis is a rare clinical entity, clinicians should remain vigilant about common presentations of this rare entity, early diagnosis and prompt treatment is crucial to prevent progression to renal failure.

Utility of clinical parameters, cystourethroscopy, and magnetic resonance imaging in the preoperative diagnosis of urethral diverticula.

INTRODUCTION AND HYPOTHESIS: Our purpose was to assess the accuracy of history and physical, cystourethroscopy, and magnetic resonance imaging (MRI) in preoperative diagnosis of urethral diverticula. METHODS: This was a retrospective review of all patients who underwent surgical excision of periurethral masses between 1998 and 2009. Presenting symptoms and examination and cystourethroscopic findings were noted. A single pathologist reviewed all cases and provided the reference standard for the diagnosis of a diverticulum. A single radiologist reviewed all preoperative MRI studies. Sensitivities, specificities, and positive and negative predictive values (PPV, NPV) were determined. RESULTS: Diverticula were diagnosed in 36/60 (60 %) patients. Transurethral fluid expression on palpation and recurrent urinary tract infection (UTI) had high PPV. Sensitivity, specificity, PPV, and NPV, respectively, for cystourethroscopy were 33 %, 100 %, 100 %, and 42 %; for MRI, these were 100 %, 83 %, 92 %, and 100 %. CONCLUSION: These data reinforce the utility of transurethral fluid expression for preoperative evaluation of urethral diverticula. Additionally, MRI is an excellent adjunctive diagnostic tool and may assist in establishing the diagnosis when there is high clinical suspicion of a urethral diverticulum but nonconfirmatory findings on cystourethroscopy.
